Scar from piercing while pregnant; is there anything that can be done? (Photos)

I got my belly button pierced before I knew I was pregnant, and as my stomach stretched it didn't heal right. The scar stretched with it, I eventually took it out, and repierced it twice after I had my son to try and cover this scar but failed because of infections. I'm giving it biocorneum twice a day and I got a steroid shot to try and break the scar tissue up inside, but its the color that makes it so noticeable. Is there anything that can be done?
